The combined valvrechamber O, E, and theinet n p a e a PQ tse 3b 0W the cylinder for convenience gandcondfuctingoff watervof cono-ved results are secured in th eloptheengine, The cylinder cham- -1 :prev-idedwith the usual piston A, nan-we,J,te-Wh is Secured he tap- "Eam-rner H', which slides upon the stay redL. T st am p s, as, e d ng o the .Qfyfinderchambefnl to the valve,chamber }E, are adapted to register with the steam inductignychanrberfi,and the annular eduction channels, h and h.

Theva-lve D, is formed with solid-ends p and gqand nwith a centrallongitudinal stem, and co ta ns he c ra o g di passa and the endpassages on ports d" and d, -=w-hichare adapted to register with theports e, in thew-allot the cylinder I, and comrn tn-ica-tewiththeinterior of the-valve cham- ?-b,e,r E, at each end thereof. In the solidends 111 and q of valve D, and at the periphery ';there,of,'are formedthe eduction ports, I) and gbflwhich are adapted to connect the valveLchanrberwith the passagesa, a, leading to the exhaust oreduct-ienpasjsages f and f, which connect with the exhaust port F. Thelarge recess at the middle portion of valve D, around its longitudinalstem forms the steam ,chest or induct-ion port 1.0, of the valve, whichby means of which arrangement chest or -port--is made to register withthe 1' 11ports, during the reciprocating mqyement of the valve. The stemof the valve is rovidedi ear its opposite ends with the of the valve,its red and cams for partiy ro valve, there arefornied the annularchannels irei la 'disk-li e ebut en e, dflfer v or exhaust ports, 12.,h, which are so placed as to register with the induction ports g, g, andwith the exhaust passages f, f, during the reciprocating movements ofthe valve. The longitudinal stem of the valve is provided with lateralopenings, 11., connecting chamber 0, with the longitudinal passage (1.

In the base of the engine (Figs. 2 and 3) are formed the two steaminduction ports, a, c, and the eduction ports, F, F. Two of the ports,as c, F, are closed by plugs v, w, and two of them are connected bypipes in the usual manner.

The valve rod, G, has secured to it an oscillating bar, K, provided withthe two opposite inclines or cam faces an and m, for engaging with thetappet pin it", by means of which the valve D is given a rotary oroscillating motion for alternately connecting the eduction ports I) andb, in its solid ends with the exhaust passages a and a, for permittingthe escape of steam from the valve chamber between the opposite ends ofthe valve and the heads B, B, during the reciprocating movement of thevalve.

The operation is as follows: Steam is admitted through the inductionport, 0', into the large central chest or induction port 0, in valve D,and in the position of parts shown in Fig. 1, passes through port g,into the end B, of the steam cylinder I, moving piston A, from left toright, as indicated by the arrows. The valve D, having been previouslythrown to the left, as shown, steam escapes from cylinder I, throughport, 9', exhaust port, h, and passage f and at the same time live steamis passing from chamber 0 by openings at, through the central passage d,induction ports, 62" and e", in the end of chamber E, adjacent to headB, thereby holding valve D to the left against the head B. As the pistonA, moves to the right hand end of cylinder I, the tappet pin, h", bearsagainst the cam surface, m on the oscillating bar K, thereby oscillatingvalve D, so as to close communication between the ports d and e", at endq and at the same time connect exhaust port I), in the valve withexhaust passage, 0., leading to exhaust passage f; also at the same timecausing induction port, d, in the end 19 of the valve to register withthe induction port, e, and close communication between eduction port I)and exhaust passage a, where.- by steam is admitted between end 13, ofthe valve and cylinder head B, so as to throw valve D, to the oppositeend of its chamber. This movement of valve D, causes the large inductionport 0, to register with port, g, admitting live steam into the end B,of piston chamber or cylinder, I, and at the same time causes theexhaust port, h, in the valve to register with the port g, and with theexhaust passage f, leading to exhaust port F. The movement of the pistonfrom right to left now causes the tappet pin, h, to bear against camface, m, and again oscillate valve D, so as to close communicationbetween the induction ports, d, and e and open communication between theeduction ports I), and exhaust passage, a, at end 19, of the valve, andalso open communication between induction ports cl" and e", and closecommunication between the eduction port I), and exhaust passage, a, atthe end 11, of the valve, so that live steam again flows through passage(1 and ports at" and e", into chamber E, between end q, of the valve andcylinder head B, again throwing the valve to the left hand end of itschamber E, so that steam is again admitted through port, g,and exhaustedthrough port, 9', as at first above described.

The operation is very simple and the movements are efiected in rapidsuccession, so as to operate the piston at the desired speed.

The single large central steam chest or in duction port, 0, adapted toregister with both of the ports, g and g, of the steam cylinder is anadvantageous feature of my invention. The longitudinal passages and theinduction ports in the opposite ends of the valves and the exhaust portsand passages at opposite ends of the valve for the passage of steam toreciprocate the valve are also important features of my invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a steam engine, a single reciprocating and rotatable oroscillating balanced valve, having a central steam chest or inductionport and two eduction channels or ports, one in each of its solid ends,separated from said induction port by circular abutments, said portsbeing adapted to register with the cylinder ports and the exhaustpassages and port and said solid ends of the valve being also providedwith eduction ports registering with exhaust ports, in combination withsteam inlets at the ends of the valve chamber, and means for oscillatingthe valve for controlling the steam inlets and eduction ports at theends of the valve chamber, substantially as described.

2. In a steam engine, a reciprocating balanced steam valve, having acentral induction port and exhaust ports at each end thereof forsupplying steam to and exhausting it from the piston cylinder and alsohaving interior steam passages and ports for conductinglive steam to theends of the valve chamber for reciprocating the valve, substantially asdescribed.

3. Ina steam engine, the combination with a valve chamber of thereciprocating and rotatable or oscillating balanced valve, having acentral induction port, an abutment and exhaust port at each endthereof, a central longitudinal steam passage and a small induction portin each end registering with an induction port in the wall of thechamber, also a small eduction port in each end adapted to register withan exhaust passage, and means for rotating or oscillating the valve,substantially, as described.

. 5. In asteam engine a-single reciprocating and oscillating balancedvalve having a central steam chest or induction port and two eductionports, one in each of its solid ends, in combination with the valvechamber having steam inlets and exhaust ports .for reciprocating thevalve, the valve rod having an oscillating bar provided with camsurfaces, and a tappet pin connecting with the piston rod and bearing onsaid cam surfaces for 0s,- cillating the valve, substantially asdescribed. In testimony whereof Iaffix my signature in presence of twowitnesses.
